10. RAID1
RAID1 (Redundant Array of Independent Disks Level 1) is a technology generally referred
to as "Disk mirroring". The RAID1 is the Disk mirroring by the RAID controller. The RAID1
constructs the system that two HDDs are combined and managed as one RAID1 system
(array). Should one HDD fail, you can read correct data from the other HDD. RAID1 uses two
HDDs but the capacity available is only equal to the capacity of one HDD.
